Outline of Final Research Achievements

In SOFC of the electrolyte thickness 1.0 mm, the maximum power density of 29.8 mW cm-2 was able to be achieved at 500 °C. The conductivity at 500 °C of oxide ionic conductor, lanthanum silicate, of the SOFC electrolyte has improved to 0.02 S cm-1. High interfacial resistance on the electrolyte-electrode has decreased by using samarium stabilized ceria for the buffer layer.
